Abstract

During the spring of 2007, a pathogen identified as Pestalotiopsis longisetula (Guba) X.A. Sun & Q.X. Ge was isolated from lesions on stems and leaves of strawberry (Fragaria ananassa D.) from Golestan and Kordestan Provinces of Iran. On PDA (potato-dextrose-agar), it produced a pinkish-white colony with black, slimy conidial masses protruding from the surface. After eight days incubation at 23oC, the colony diameter reached 90mm on PDA. Conidia produced in culture were 5-celled, long fusiform, straight or slightly curved, hardly constricted at septa, with a tapering base (Fig. 9). They measured 21-29 × 6-7 µm, with three apical setulae of 20-32 µm long and a basal pedicel of 3-6 µm long. The three intermediate colored cells were 17-20 µm, the upper two usually fuliginous, black at septa and walls, lowest cell olivaceous. The apical cells were hyaline, long conic to cylindrical. This description matches that of P. longisetula (GUBA, E.F. 1961. Monograph of Monochaetia and Pestalotia. Harvard University Press. 342 p.).The pathogenicity of two isolates was determined on leaves and petioles of 8-week old strawberry plants inoculated with a conidial suspension of the fungus (1 × 107 conidia/ml), incubated in a moist chamber for three days and then transferred to growth chambers at 23oC with a 12-h photoperiod. Three plants were inoculated with each isolate. Symptoms appeared on stems and leaves five days after inoculation. Symptoms did not appear on control plants inoculated with sterile distilled water. The same fungus, P. longisetula, was re-isolated from these symptoms. This is the first report of P. longisetula from Iran.
